Description

Shuttleless weaving machines with two rapiers are already known, moving in the guides of the fixed boxes and converging together in the middle of the throat to transfer the loop of weft yarn from the hook, which feeds on the hook of the receiving rapier.

In machines of this kind, for example, for the weft of a weft thread of sleep with a pair of scissors, piar clips on each side of the machine are mounted in a fixed box together with the transfer bodies of the weft thread from one clamp to another.

Such a machine, however, did not provide the possibility of working at great speeds, due to the insufficiently accurate transmission of the thread from the pickup hook of the receiving rapier.

The described machine eliminates the noted phenomenon and is distinguished by the fact that in order to clearly transfer the yarn at high speeds, the free ends of the rapiers are made interacting with the Byrd teeth during the weft yarn transfer.

Fig 1 shows a machine, front view; in fig. 2 is the same side view in FIG. 3 is the same, top view; in fig. 4-surf machine mechanism, side view; in fig. 6 diagrams of the arrangement of the mechanisms for feeding and measuring the weft thread of the machine and in different periods of its operation; in fig. 7 is a longitudinal section of the mechanism in two projections; in fig. 5-fabric, top view.

To control each of the rapiers 12 of the machine, turning on the axis 13 corresponding to the sliders and spring-loaded in the direction of the reed 3, the shoulder strap M of the angular lever W was used, which was connected with vodka 11 to the slider. The angular lever 10 is mounted on the axis 15 of the fixed arm 20 of the machine frame and is connected to the crankshaft crankshaft M / one link 9 with end ball spikes J. The rapier slider moves in fixed guides 4 at an angle other than straight to the longitudinal axis of the machine This angle is chosen so that the loose ends of the rapier inter # 70084

 at the entrance to the pharynx, the catch of the feeding rapier applies a loop of such thread on the hook of the hinge of the rapier, the peeler of which of the rapier diverges from the middle of the reed. The latter is established (Fig. 4) between the bar 6 and the actor 7 on the levers 2, the rotary on the non-movable axis 4 and the hinged joint of the 5th axles 5 with the shaft knees /.

During the two complete maneuvers of the rapnr, there is a gasket in the throat of two caps in the form of one loop, the bow of which is on the side of the feeding rapier.

The next two complete vibrations of the rapier correspond to the use of the left rapier as a receiver and the right one as a giving (phi 6, d, s, pc).
